摘要: Abstract A h -adaptive finite element strategy for acoustic problems is presented. The key features of the are error estimation, adaptive mesh generation and remeshing, analysis. estimation has been performed using superconvergent patch recovery technique prime variables approximation (SPRD). For commercial software package I-DEAS applied. Finite analysis SYSNOISE. Numerical examples shown to illustrate properties SPRD procedure proposed strategy.
